I was originally thinking of selling vape tips but the market is over saturated and selling FDM drip tips is not realistic so... Enjoy :)!
Cyclone (it has a turbine shape inside which should make the smoke "tornado")
Apple - Traditional Tobacco pipe look
Full Bent - modelled after and actual tobacco pipe design
modelled for 510 and 810 nozzles. or something like that I don't vape i forget the name
Print from inside out to increase surface quality
If you generate automatic supports for teh cylone it will fill the inside of it and not allow flow
